Was just wondering if anyone knew of any way to force modesetting on for r200 series cards, specifically RV250
I believe they don't have it on because it breaks 3d; well the 3d isn't very good anyway...
so I want to try KMS and Plymouth.

The vga=0x318 is not necessary correct for vesafb. That one doesn't work on my system, for example. I can use 0x31A or any of a number of others.

The article also says that R600 works with KMS, but that doesn't seem to be the case yet (for stock Fedora/Rawhide, anyways). As stated on the Open Source AMD/ATI boards, that still requires building your own DRM and releated bits from the modesetting-gem branch of mesa/drm.

KMS in Rawhide definitely isn't working on R600 on my machine without using vesafb, anyways.

Add radeon.modeset=1 to the kernel command line for r100/r200s

R600 the code is there, the PCI IDs are not, I'll probably enable them in rawhide post-F10, it was just a matter of bad timing.

It's in a laptop if that matters. Tried many of the combinations of radeon.agpmode=-1/1/2/4/8 with and without radeon.modeset=1.

Didn't matter what radeon.agpmode was set to.

I suppose since this is unsupported a bug report wouldn't be an option.
The Xorg.0.log looks really weird to me...why is vesa in there?(although I haven't ever seen an Xorg log from a KMS system before.)

It would also be nice to see Plymouth (or some adaptation of it) supported by other Linux distributions.

Supported? It's open source, just install it in Ubuntu if you want it in Ubuntu. So what if it doesn't come with it by default. I guess that's one reason for rolling your own distro, but yeah I hope most desktop Linuxes will come with this software in the future because most users will want it I reckon.

Linux needed a boot process sleek enough to match Mac's. I hope the next step will be to implement this in the Linux BIOS as well, so that it will be possible to go from power on all the way to your desktop with no flickering or changing of resolutions whatsoever.

It's pretty clear that you can NOT just install Plymouth into a distro and actually have it work. It needs tight integration with the distro to actually work. It needs to properly inserted into the initrd (which will require an entirely different set of commands and scripts than Fedora uses) and the init system needs updates to communicate with Plymouth properly. Plus I'd imagine you'd need to change the GDM startup to use the new features to not reset the video mode and get smooth fade-in.

If Ubuntu/Debian/SUSE/etc. want Plymouth, the distro engineers are going to have to integrate it, which will take a fair amount of effort.

It is not at all something a regular user -- or even a moderately advanced user -- would be expected to know how to do properly.
